2026 COMPLETE QUESTIONS AND
SOLUTIONS GRADED A+
◉ the __________ ratio is the name given to the air fuel ratio required
for all the hydrocarbons within a given mixture to completely burn.
Answer: stoichiometric
◉ which form of induction ice within a carburetor is most likely to
occur at low power settings?
Answer: throttle
◉ what component of a fuel injection system has a ball valve that
closes on engine shut down to maintain pressure within the fuel
line?
Answer: flow divider
◉ what component of a float type carburetor is connected directly to
the throttle control?
Answer: butterfly valve
,◉ True or False. Carburetor heat should be applied BEFORE
carburetor icing conditions are noted on the appropriate gauges.
Answer: True
◉ What is the proper procedure for setting best power in the piper
archer?
Answer: use the EGT gauge and lean the mixture until the first
cylinder peaks (reaches it's hottest setting) then enrichen the
mixture until that cylinder is 100 F less than the noted peak value
◉ which form of induction ice is associated with the temperature
within the venturi caused by fuel changing matter state?
Answer: fuel evaporation
◉ what is the approximate air:fuel ratio where the most power will
be produced by the burning of the mixture within the cylinder?
Answer: 12:1
◉ Which form of induction ice can a carburetor or fuel injection
system be susceptible to?
Answer: impact
, ◉ what component of a float type carburetor solves the problem
that at idle RPM's there is not enough airflow to sufficiently draw
fuel into the main discharge nozzle?
Answer: acceleration system
◉ what type of fuel system can be found on the piper archer?
Answer: fuel-pump system
◉ what is meant by the term "wet wing?"
Answer: term used to describe an airplane that uses its wing
structure as a fuel tank
◉ if the main fuel vent on one of the piper archer's tanks became
clogged, what would happen?
Answer: nothing, the pilot would be able to continue to draw fuel
from the tank
◉ the total usable fuel capacity of the piper when filled to tabs is
________ gallons.
Answer: 34
◉ How can the risk of water freezing in fuel be reduced?
Answer: drain fuel tanks prior to flight or use an additive such as
prist to the fuel to lower the freezing point
